===Soils===
The soils of Andalusia can be divided into three large areas: the [[Sierra Morena]], [[Cordillera Subbética]], and the [[Baetic Depression]] and the [[Surco Intrabético]].<ref>{{cite journal |last=Moreira |first=J.M. |title=Suelos y degradación edáfica |journal=Carel: Carmona: Revista de estudios locales |number=3 |issn=1696-4284 |pages=971–986 |language=es |url=http://dialnet.unirioja.es/servlet/fichero_articulo?codigo=2328574&orden=84885}}</ref>

The Sierra Morena, due to its morphology and the acidic content of its rocks, developed principally relatively poor, shallow soils, suitable only for forests. In the valleys and in some areas where [[limestone]] is present, deeper soils allowed farming of cereals suitable for livestock. The more complicated morphology of the Baetic Cordillera makes it more heterogeneous, with the most heterogeneous soils in Andalusia. Very roughly, in contrast to the Sierra Morena, a predominance of [[base (chemistry)|basic]] (alkaline) materials in the Cordillera Subbética, combined with a hilly landscape, generates deeper soils with greater agricultural capacity, suitable to the cultivation of olives.<ref>{{cite book |author=Consejería de Agricultura y Pesca |chapter=Suelos |title=Atlas Agrario y Pesquero de Andalucía |year=1992 |publisher=Junta de Andalucía |language=es}}</ref>

Finally, the Baetic Depression and the Surco Intrabético have deep, rich soils, with great agricultural capacity. In particular, the [[alluvium|alluvial]] soils of the [[Guadalquivir]] valley and plain of [[Granada]] have a [[loam]]y texture and are particularly suitable for intensive irrigated crops.<ref>{{cite web |url=http://www.juntadeandalucia.es/medioambiente/web/Bloques_Tematicos/Estado_Y_Calidad_De_Los_Recursos_Naturales/Suelo/Criterios_pdf/Tipologia.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.juntadeandalucia.es/medioambiente/web/Bloques_Tematicos/Estado_Y_Calidad_De_Los_Recursos_Naturales/Suelo/Criterios_pdf/Tipologia.pdf |archive-date=9 October 2022 |url-status=live |title=Tipología de los suelos en la comunidad andaluza |access-date=21 July 2008 |author=Consejería de Medio Ambiente de Andalucía |language=es}}</ref> In the hilly areas of the countryside, there is a double dynamic: the depressions have filled with older lime-rich material, developing the deep, rich, dark [[clay]] soils the Spanish call ''[[bujeo]]'', or ''tierras negras andaluzas'', excellent for dryland farming. In other zones, the whiter ''albariza'' provides an excellent soil for [[vineyard]]s.<ref>{{cite journal |last=Perea |author2=González, P. |title=Origen, clasificación y caracterización de los suelos de la Campiña de Carmona |year=2005 |journal=Carel: Carmona: Revista de estudios locales |number=3 |issn=1696-4284 |pages=971–986 |language=es |url=http://dialnet.unirioja.es/servlet/fichero_articulo?codigo=2328574&orden=84885}}</ref>

Despite their marginal quality, the poorly consolidated soils of the sandy coastline of Huelva and Almería have been successfully used in recent decades for hothouse cultivation under clear plastic of strawberries, raspberries, blueberries, and other fruits.
